Aim-TTi TGR2051 Synthesised RF Signal Generator

Description

The Aim-TTi TGR2051 Synthesised RF Signal Generator is a high-performance, accurate touchscreen radio frequency generator with Sweep functions and flexible analogue modulation. It is ideal for development, test and service work.

Amplitude and Frequency

The Aim-TTi TGR2051 Synthesised RF Signal Generator has a frequency range of 150kHz to 1.5GHz, an accuracy of 1ppm (<1ppm drift in the first year), a setting resolution of 10Hz, and high stability. Additionally, it has an amplitude range of -127dBm to +13dBm with a setting resolution of 0.1dbm. The amplitude can be set in either dBm, dBµV or linear volts.

Furthermore, the Aim-TTi TGR2051 Synthesised RF Signal Generator features low phase noise providing a high signal purity: < -117dBc/ Hz (typical) at 1GHz output and 10kHz offset.

Sweep Function

Inclusion of Sweep functions means the Aim-TTi TGR2051 Synthesised RF Signal Generator can test a full range of input conditions efficiently using signals of varying frequency and/or amplitude. The Aim-TTi TGR2051 Synthesised RF Signal Generator is able to perform Step Sweeps and List Sweeps.

Step Sweeps are created according to a formula over a specified number of points (2 to 1000); they must include start and stop amplitude/ frequency values and dwell times following SYNC at each point. Step Sweeps can be set to run in either direction using linear or logarithmic spacing. The Aim-TTi TGR2051 Synthesised RF Signal Generator features a 5ms sweep settling time.

List Sweeps can be used to test known problematic frequencies within a setup. It analyses the response at set frequencies and amplitude-dwelling onset values for the duration of a user-specified time period. Lists can be created via the front panel or on a PC and subsequently downloaded to the Aim-TTi TGR2051 Synthesised RF Signal Generator using a remote interface.

Step Sweeps and List Sweeps can be performed as a single sweep or can be programmed to continue in a loop prompted by an internal, external or manual trigger. The Aim-TTi TGR2051 Synthesised RF Signal Generator also includes options for complex sweep triggering enabling control of each sweep point and the sweep as a whole.

Graphic User Interface (GUI)

Parameters such as amplitude and frequency can be configured using the Aim-TTi TGR2051 Synthesised RF Signal Generator’s simple and user-friendly touch-operated GUI. All parameters are easily accessible via the Aim-TTi TGR2051 Synthesised RF Signal Generator’s menu screen and can be edited using the hard keys or the rotary knob, improving the ease and efficiency with which tests can be configured.

It is also possible to program the Aim-TTi TGR2051 Synthesised RF Signal Generator via its USB and LAN interfaces.

Readings and key information are displayed simultaneously on the Aim-TTi TGR2051 Synthesised RF Signal Generator’s 4.3-inch, colour LCD.

Internal Modulation Pattern

The carrier signal can be modulated using operator-specified patterns created using the Aim-TTi TGR2051 Synthesised RF Signal Generator’s pattern generator. As a result, the user can create a unique pattern of up to 16384 states via the front panel or PC. Modulation patterns created on a PC can be imported via the Aim-TTi TGR2051 Synthesised RF Signal Generator’s LAN (LXI) and USB interfaces. These patterns can be triggered externally, internally, manually or remotely.

Analogue Modulation

The Aim-TTi TGR2051 Synthesised RF Signal Generator includes a built-in DDS generator which provides Sine, Square, +Ranp, -Ramp and triangle waves, which can be applied in AM, FM or PM forms from the internal modulation source at frequencies ranging from 1mHz to 1MHz.

Furthermore, via the MOD in/out, located on the Aim-TTi TGR2051 Synthesised RF Signal Generator’s rear panel, external analogue modulation signals can be applied to the carrier waveform.

Memory

The Aim-TTi TGR2051 Synthesised RF Signal Generator features a 4GB non-volatile memory to which multiple setups (up to 1000), sweeps and modulation patterns can be saved.

Compatibility

The Aim-TTi TGR2051 Synthesised RF Signal Generator can be integrated into new and existing systems using the SCPI command set. It supports an extensive library of SCPI commands which can be used to simplify setups and automate systems.

Furthermore, the Aim-TTi TGR2051 Synthesised RF Signal Generator can replace legacy Aim-TTi TGR1040 and TGR2050 RF Generators in existing systems, as it supports legacy remote control command sets.

LabView & IVI Driver

The Aim-TTi TGR2051 Synthesised RF Signal Generator includes an IVI-COM/ IVI-C driver for Windows facilitating compatibility with LabView, LabWindows and Keysight VEE.

Ergonomic

The Aim-TTi TGR2051 Synthesised RF Signal Generator is lightweight and compact ensuring that it takes up minimal bench space. It is housed in a 2U ½ rack case and can be mounted using a compatible 2U 19” rack kit (NOT included).

The Aim-TTi TGR2051 Synthesised RF Signal Generator is a high-quality, precise and versatile RF generator optimised for development, test and service work.
